My parents are visiting for Passover, so we decided to take a Chol Hamoed trip today.  Our ultimate goal was the mining tour at Sterling Hill Mining Museum.  On the way, we visited Jungle Habitat, an abandoned drive-through safari attraction in West Milford, New Jersey.  It closed in 1976, but remnants of the old roads persist:

Adjacent to Jungle Habitat is the Greenwood Lake airport, which uses the remodeled interior of a Lockheed Constellation as the flight school office:

At last we arrived at the Sterling Hill Mining Museum.  This site was an active copper and zinc mine from the 1630s to 1986.  Our first stop was the miner’s locker room, which has been remodeled into a museum space:

This area is famous for its fluorescent minerals.  Of the 3,500 minerals known, 357 can be found in this area, 91 of which are fluorescent, the highest concentration anywhere on Earth.  35 minerals are only found in this area:

Preparing to enter the mine:

The mine has 35 miles of tunnels on many levels, the lowest being 2,600 feet below the surface.  The water table here is about 70 feet below the surface, so once the mine closed and the pumps were turned off, the lower levels flooded.  The tour traverses a portion of this upper level:

After the mine tour, we entered another exhibit space with fluorescent minerals:
